Fuel Heating Values: Natural gas
Fuel combustion properties — higher/lower heating values (HHV/LHV), stoichiometric air requirements, combustion product yields (CO2, H2O), flammability limits, ignition and adiabatic flame temperatures, and ultimate (elemental) analysis for gaseous fuels, liquid fuel oils, solid coals, biomass, and waste fuels
